Chemicals accidents cause various hazards and a lot of damage. In order to prevent chemical accidents, various risk assessments are conducted in Korea. Among them, the Bow-tie risk assessment technique is a technique that displays the cause and effect of an accident on a line and is used widely in foreign countries. The semi-quantitative Bow-tie technique is a technique based on LOPA(Layer of Protection Analysis), which evaluates the appropriateness of protective measures derived from qualitative risk assessment. Acrylic acid is used as a main raw material for polymeric materials, and interest has been increasing due to the problems of supply and safety caused by the recent BASF fire accident. In this study, we compared the Bow-tie technique with the risk assessments currently used in Korea, and conducted a risk assessment on the polymerization process, which is the main use process of acrylic acid. As a result, a total of 8 new protective measures were derived, and it was verified by semi-quantitative Bow-tie technique. Based on the result of Bow-tie risk assessment, the acryl resin process was improved to reduce the risk. This confirms the usefulness of qualitative Bow-tie risk assessment and semi-quantitative Bow-tie risk assessment, and may be useful in other domestic chemical processes.

This study conducted network analysis by utilizing text mining among keywords extracted from the causes of industrial accidents. To address this, Textom was utilized to examine the causes of industrial accidents covered in the abstracts of research papers on ‘risk assessment’, and attempted to search their correlation. Keywords including “chemicals”, “fire”, and “explosion” had a high frequencies in occurrence, and many studies on risk assessment have been conducted around “chemicals”. Moreover, it is necessary that often cause industrial accidents are approached with risk awareness. After the CONCOR analysis, four clusters were formed which will help identify hazards and risk factors in risk assessments, adequately analyze assessment contents, and decide risk assessments.

소듐, 리튬금속화재에 대한 불활성 기체 소화약제의 적용성 분석

최명락(Myung Rak Choi),이건석(Lee, Geonseok),이승현(Seung Hyun Lee) 한국위험물학회 2020 한국위험물학회지 Vol.8 No.2

This study aims to assess the application of an inert gas fire extinguishing agent for extinguishing metal fire. Sodium and lithium were used as the metallic combustibles. Testing was executed by altering the oxygen concentrations in the order of 21, 6, 4 % by using inert gas fire extinguishing agents including IG-01, IG-541, and IG-100. Since metal features risks of dispersion and explosion, fire was generated by after having adjusted the inert gas extinguishing agent concentration in advance. Regarding the test results, The lower the oxygen concentration, explosion occurred without the manifestation of sparks or a flame. In addition, it was possible to obtain the same results for all of the fire extinguishing agents, namely, IG-541, IG-100, and IG-01. Through this test, it was possible to confirm the characteristics of metal fire and the applicability of IG-01, IG-541, and IG-100 to metal fire. Although it was confirmed that IG-541, unlike the results of NFPA 12 and NFPA 2001, can be applied to metal fire, it is deemed to be the result of the difference in the testing conditions.

Among the various fields for securing the safety of a petrochemical plant, facility safety management is one of the very important parts. In general, piping equipment of a petrochemical plant is determined to continue use through risk assessment and sample inspection, but studies on whether this method is suitable for the safety of long-term plant is very insufficient. This study focuses on how to verify the integrity of equipment by conducting non-destructive inspection of welded parts of hydrogen piping equipment used for a long period of time. Radiographic Test (RT) method was applied to a process built in 1990 producing paraffin from kerosene. In summary, 2.8% of inspected welding points were found to be inadequate and independent service pressure. Most of the defects were found at the pipeline less than 2 inch diameters. Through this study, potential problems in welded parts of hydrogen piping equipment of a petrochemical plant in long-term use were confirmed through empirical non-destructive testing. Based on these results, six plans for piping facility management to secure fundamental safety of petrochemical plants were presented. Based on the results of this study, it is intended to be of great help in establishing the policy and direction of facility management to ensure the fundamental safety of welded parts of hydrogen piping facilities used for a long period of time.

Study on the Response Technique Development against the Chemicals Release Accidents

This study aims to provide reliable technical data and guidelines to initial response agencies, similar to accident management technical reports of the US and Canada. Technical information and graphic data contain item to figure out information needed for initial response and matters to improve in existing chemicals information guidebook. We also collected and reviewed the Canada’s TIPS(Technical Information Problem Spills), US EPA’s hydrogen fluoride documents, domestic and foreign literature on applicability tests of control chemicals, and interview data, and then suggested items to be listed in the technical guidelines. Additionally, in order to establish on-site technical information, the study investigated data on analysis method by environmental media in Korea and other countries as follows and presented the result as follows: ① emergency shutdown device, safety device, lock valves, earthing, dike, transportation pipes, scrubber, detector ② literature research and field investigation on distribution type, characteristics of transportation and storage (container identification, lock device, earthing) ③ emergency leak prevention, leak prevention method, emergency response measures such as rainwater gully cutoff and detour, classification and identification by type of storage and transportation facilities ④ Detection method using portable equipment in home and abroad, process test method, environmental standard and exposure limit Furthermore, the study presented 6 key information items for accident response so that each information item can be mutually linked and people in charge of initial response can easily identify the information.
